DETAILED DESCRIPTION

Hereinafter, a control method according to one exemplary embodiment will be described with reference to the drawings.

Exemplary FIG. 1 is a functional block diagram of a game system according to one particular exemplary embodiment. The game system may include a server apparatus 1 and a terminal apparatus 2, and the server apparatus 1 and the terminal apparatus 2 may communicate with each other over a network. According to an exemplary embodiment, the number of server apparatuses 1 and the number of terminal apparatuses 2 may not be limited to specific numbers; for example, each may comprise one or multiple devices. The terminal apparatus 2 may be, for example, a portable terminal or a desktop terminal, as desired.

The server apparatus 1 may include a control unit 11, an identifier output unit 12, an identifier obtaining unit 13, a game content output unit 14, a hint providing unit 15, a reset unit 16, a display information output unit 17, a communication unit 18, and a storage unit 19. The server apparatus 1 may provide a game using game media to users over a network. Note that, although a description is given of functions of the server apparatus 1 according to one exemplary embodiment, the description is not intended to exclude other functions that are included in the server apparatus 1.

The control unit 11 may be a processor, such as a central processing unit (CPU), which controls various operations of the server apparatus 1.

The identifier output unit 12 can obtain identifiers from the storage unit 19 described below and may output the identifiers to the terminal apparatus 2.

The identifier obtaining unit 13 may obtain an identifier selected through a user operation. According to an exemplary embodiment, although the identifier may be associated with the game content, the game content may not be identifiable using the identifier. That is, it may not be possible to identify a game content using an identifier.

The game content output unit 14 may refer to the storage unit 19, may search for and obtain a game content that is, in the storage unit 19, associated with an identifier obtained by the identifier obtaining unit 13, and may output the game content to the terminal apparatus 2 as an incentive.

The hint providing unit 15 may provide a hint about an association between an identifier and a game content. For example, the hint providing unit 15 may provide a hint indicating which identifier is associated with which game content.

The reset unit 16 may reset associations between identifiers and game media in response to a user request or at a predetermined time point. The reset unit 16 may perform resetting only in a case where a certain condition is satisfied; for example, the reset unit 16 may perform resetting only when a lottery is played at least once.

The display information output unit 17 may generate information to be displayed by a display unit 22 of the terminal apparatus 2 and may output the information to the terminal apparatus 2. For example, the display information output unit 17 may generate display information that indicates the number of identifiers corresponding to game media having values equal to or larger than a predetermined value among identifiers that are allowed to be input, and may output the information to the terminal apparatus 2.

The communication unit 18 may be an interface for transmitting and/or receiving information to and/or from the terminal apparatus 2. The communication unit 18 may perform communication by at least either wired connection or wireless connection.

The storage unit 19 may be a memory, for example a semiconductor memory, a magnetic memory, or the like, and may store, for example, various DBs, a program for operating the server apparatus 1, and the like. Storage unit 19 may also function as a work memory. The storage unit 19 may store identifiers and game media in association with each other. The storage unit 19 may also include a game content DB 19 a, a lottery history DB 19 b, and a provided-hint DB 19 c. For each user (each terminal apparatus 2), one game content DB 19 a may be provided. The DBs included in the storage unit 19 may be stored outside the server apparatus 1 and accessed from the server apparatus 1 as needed. According to an exemplary embodiment, the identifier output unit 12, the identifier obtaining unit 13, the game content output unit 14, the hint providing unit 15, and the reset unit 16 may all be implemented as one function of a software program stored in the storage unit 19.

The terminal apparatus 2 may include a control unit 21, a display unit 22, a communication unit 23, and an input detection unit 24. According to an exemplary embodiment, other functions may also be included in the terminal apparatus 2.

The control unit 21 may be a processor, such as a CPU, which may control various operations of the terminal apparatus 2.

According to an exemplary embodiment, the display unit 22 may be, for example, a liquid crystal display, an organic electroluminescence (EL) display, or an inorganic EL display. The display unit 22 may be composed of a touch panel. In this case, the display unit 22 may display various game screens and may also function as an interface that accepts user input provided through a user operation. The display unit 22 may be externally connected to the terminal apparatus 2 and used.

The communication unit 23 may transmit and/or receive information to and/or from the server apparatus 1. The communication unit 23 may perform communication by at least either wired connection or wireless connection.

The input detection unit 24 may be any input device that includes a mechanical push button or a touch sensor. The input detection unit 24 may detect an input operation. An input operation may be any operation; for example, it might be an operation such as pressing, touching, tapping, contacting, approaching, or the like.

An exemplary embodiment of the game system may also be described. In the game system according to this embodiment, the user of the terminal apparatus 2 may be able to log in to the game system and participate in a game or in an event in a game by using game media.

A game may include game activity such as fighting, a quest, a mission, or the like that is provided by the game system. Participating in a game may include, for example, performing fighting, a quest, a mission, or the like, or logging in to the game system in order to perform fighting, a quest, a mission, or the like.

An event in a game may be any event or the like that is held by the game system in a certain period, and may indicate an event in which an activity is performed by a user. This may include, for example, balloting, ranking forecast, contention for precedence, and/or a battle. Participating in an event may indicate performing an activity, such as balloting, ranking forecast, contention for precedence, and/or a battle, or logging in to the game system in order to perform an activity mentioned above.

A game content may be electronic data used in the game. Examples thereof may include a card, an item, a character, an avatar, and a virtual currency used in the game. A game content may include, for example, electronic data that can be obtained, possessed, used, managed, exchanged, combined, enhanced, sold, discarded, and/or donated by a user in the game in accordance with progress of the game; however, the form of using a game content may not be limited to those explicitly described herein. Status information that is unique to a game content may indicate a fighting strength, such as an offensive strength and a defensive strength, of the game content, a fighting device, such as an offensive device and a defensive device, of the game content, the cost of the game content, skill information about the game content, information about an avatar, which is the game content, attributes of the game content described below, an index indicating the degree of rarity of the game content described below, and the like. According to an exemplary embodiment, rarity may be merely one example of a parameter that represents the value of the game content, and therefore, other parameters relating to the value may also be used. Examples of attributes of a game content may include a water attribute, a fire attribute, a thunder attribute, a light attribute, a darkness attribute, and the like. Specifically, according to one exemplary embodiment, AT01 may indicate the water attribute, AT02 may indicate the fire attribute, AT03 may indicate the thunder attribute, AT04 may indicate the light attribute, and AT05 may indicate the darkness attribute. The index indicating the rarity of a game content may be represented by any of a plurality of classes, such as normal (N), rare (R), super rare (SR), hyper rare (HR), and double-super rare (SSR), for example, with the degree of rarity increases in this order from least rare (N) to most rare (SSR). In this embodiment, a description may be given while assuming that a value VA is highest, and the value may decrease in the order of the value VA, a value VB, and a value VC.

According to an exemplary embodiment, the game system may perform a first lottery process in response to a user request or at a predetermined time point. In the lottery process, the identifier output unit 12 of the server apparatus 1 may refer to the game content DB 19 a that may store therein identifiers and game media that are provided to the user of the terminal apparatus 2 in association with each other. An example of the game content DB 19 a is illustrated in FIG. 2. In this embodiment, the description is given while assuming that a game content is an item.

The identifier output unit 12 may also output identifiers to the terminal apparatus 2 so as to allow the user to input an identifier. The user of the terminal apparatus 2 may input an identifier while viewing an image displayed by the display unit 22. As illustrated in FIG. 3, the user of the terminal apparatus 2 may input “557” as an identifier. At this time, the input detection unit 24 may detect the input of “557”. When the user selects a key K1, the control unit 21 may determine that “557” has been selected and may output “557” to the server apparatus 1 via the communication unit 23. According to certain exemplary embodiments, an identifier is a number, such as “557”, or may be other than a number. For example, an identifier may be expressed in a language specific to each country, namely, by alphabetic characters, kanji characters, hiragana characters, katakana characters, or the like or may be expressed by symbols. Alternatively, numeric characters, alphabetic characters, kanji characters, hiragana characters, katakana characters, symbols, and the like may be combined, as desired. Note that the number of digits and the number of characters of an identifier may be set as desired.

Still referring to the previous exemplary embodiment, when the identifier obtaining unit 13 of the server apparatus 1 obtains the user's input of “557”, the game content output unit 14 may refer to the game content DB 19 a again, and may search for and obtain a game content corresponding to “557”. As illustrated in FIG. 2, a game content corresponding to “557” may be 11777. The identifier obtaining unit 13 may store “557” input and may be selected by the user, for example, in the lottery history DB 19 b illustrated in FIG. 4.

The game content output unit 14 may output the corresponding game content (11777) to the terminal apparatus 2. When obtaining the game content, the display unit 22 of the terminal apparatus 2 may update the display so as to indicate the corresponding game content in an area R1 as illustrated in FIG. 5.

At this time, the hint providing unit 15 may provide a hint, which may be indicated in a region R2 illustrated in FIG. 5. According to this exemplary embodiment, the hint may say “the number in the ones column of an identifier corresponding to an item having the value VA is not 7.” A variety of hints or types of hints may be provided, as desired; for example, the hint may be a hint about the sum of the number in the hundreds column of an identifier, the number in the tens column thereof, and the number in the ones column thereof, may be a hint about a product obtained by multiplying the numbers together, or may be a hint about a subtracted value obtained from the numbers. A hint that is provided in this case may say “the sum of the numbers in the respective columns of an identifier corresponding to an item having the value VA is 10”, “the product of the numbers in the respective columns of an identifier corresponding to an item having the value VA is 192”, or “a value obtained by subtracting the number in the tens column of an identifier corresponding to an item having the value VA from the number in the hundreds column thereof and further subtracting the number in the ones column thereof from the subtraction result is −8”, for example. The hint may be a hint about a specific column of an identifier (or about a character in a specified column from the beginning in a case where the identifier is not a number). A hint that may be provided in this case may say “the number in the tens column of an identifier corresponding to an item having the value VC is 2”, “the number in the ones column of an identifier corresponding to an item having the value VB is 5”, “the number in the hundreds column of an identifier corresponding to an item having the attribute AT05 is 3 or 4”, or “the character at the beginning of an identifier corresponding to an item having the value VB is T”, for example. The hint may be a hint about the range of an identifier. A hint that may be provided in this case may say “an identifier corresponding to an item having the attribute AT02 is between 100 and 150”, or “the second character from the beginning of an identifier corresponding to an item having the value VA is an alphabetic character between J and O”, for example. Although all of the hints described above are hints relating to the values or attributes of items, the hint may be a hint relating to any status information about a fighting strength and the like of a character. A hint that may be provided in this case may say “the number in the ones column of an identifier corresponding to a character having a fighting strength of 8000 is 5”, for example. The hint providing unit 15 may store the provided hint in the provided-hint DB 19 c illustrated in FIG. 6.

The user of the terminal apparatus 2 can select a subject (item, value, attribute, or the like, for example) for which the user wants a hint. According to an exemplary embodiment, when the user selects a subject for which the user wants a hint, and notifies the server apparatus 1 of the selection by using the terminal apparatus 2, the hint providing unit 15 may generate and provide hints relating to the selected subject. According to an exemplary embodiment, the selected subject may be changeable at any time point or may be changeable when the hints relating to the selected subject have been provided by the hint providing unit 15.

In some cases, associations between identifiers and game media may be common to users, for example users that are associated with each other as a result of a friend request or in a raid. In such cases, hints may be sharable between the terminal apparatuses of the users, as desired. That is, a user can request the hint providing unit 15 to provide the user with a hint that has been provided to another user associated with the user.

According to an exemplary embodiment, the hint providing unit 15 may provide a hint only in a case where a game content output to the terminal apparatus 2 by the game content output unit 14 is a specific game content. For example, a specific game content might be a game content other than a special game content having a value higher than a predetermined value or having an attribute desired by the user.

After the end of the first lottery process described above, the game system may perform a second lottery process in response to a user request or at a predetermined time point.

According to an exemplary embodiment where a second lottery process is performed, in the second lottery process, the identifier output unit 12 may refer to the game content DB 19 a. The identifier output unit 12 may further refer to the lottery history DB 19 b and may identify identifiers that have not been selected in lotteries. After referring to the DBs, the identifier output unit 12 may output identifiers that have not been obtained by the identifier obtaining unit 13 so as to allow the user to input an identifier that has not been selected in a lottery. This may, for example, prevent the user from inputting “557”.

When an identifier is obtained, the display unit 22 may display an image as illustrated in FIG. 7. In a case where the user inputs “557” after “557” has already been selected, the display unit 22 may display a message “Already selected” as indicated in an area R3 to thereby notify the user that, this time, the user is not allowed to input “557”, which has been selected.

According to an exemplary embodiment, at this time, the hint providing unit 15 may provide a list of provided hints to the terminal apparatus 2 in response to a user request or at a predetermined time point. That is, the display unit 22 may display hints that have been previously provided, as illustrated in FIG. 8. The displayed hints can be classified according to specific subjects on the basis of any criterion. Alternatively, the hint providing unit 15 may provide a hint generated in advance each time a lottery process is performed, and may provide a list of all hints when all the hints have been provided.

The display information output unit 17 can output information about the number of identifiers that are associated with a specific game content among selectable identifiers or about the ratio of identifiers that are associated with a specific game content relative to selectable identifiers. For example, the display information output unit 17 may generate display information indicating the number of identifiers corresponding to game media having a value equal to or larger than a predetermined value and may output the display information to the terminal apparatus 2.

As a different function, the identifier output unit 12 may select a certain identifier on the basis of at least either of the hints that have been provided and the game media that have been output, and may output, to the terminal apparatus 2, an image of an input screen on which the identifier is input to the input field. According to an exemplary embodiment, the server apparatus 1 may perform a process described below.

First, the identifier output unit 12 may refer to the lottery history DB 19 b and the provided-hint DB 19 c and may obtain the lottery history and provided hints. The identifier output unit 12 may generate an identifier and, if the identifier is an identifier that is stored in the lottery history DB 19 b and that has been selected, may generate another identifier. When an identifier that is not stored in the lottery history DB 19 b is generated, the identifier output unit 12 may determine whether the identifier is consistent with the provided hints and, if the identifier is not consistent with the provided hints, may generate another identifier. If the identifier is consistent with the provided hints, the identifier output unit 12 may output the identifier to the terminal apparatus 2.

For example, it is assumed that the lottery history DB 19 b may store therein an identifier “123” and that the hint providing unit 15 has provided a hint saying “the number in the ones column of an identifier corresponding to a game content having the value VA is not 7”. In this case, the identifier output unit 12 may output an identifier that has a number other than 7 in the ones column and that is not “123”.

According to an exemplary embodiment, when obtaining the output identifier, the display unit 22 of the terminal apparatus 2 may perform display for requesting the user to select any of playing a lottery, obtaining another identifier, or cancelling, any of which the user may select. In a case where the user selects playing a lottery, the control unit 21 may detect the selection and may output the selection to the server apparatus 1, and the server apparatus 1 may perform a lottery process. In a case where the user selects obtaining another identifier, the server apparatus 1 may output, to the terminal apparatus 2, an image of an input screen on which another identifier is input to the input field. In a case where the user selects cancelling, the server apparatus 1 may not perform a lottery process, and the display unit 22 may display the previous screen, the top screen of the game, or the like.

After the user has selected an identifier, the control unit 21 may output the identifier to the server apparatus 1. Accordingly, the hint providing unit 15 can determine which identifier the user has input for the hint and can infer which game content the user wants. For example, in a state where a hint stating that “the number in the ones column of an identifier corresponding to a game content having the value VA is not 7” has been provided, when a user inputs an identifier having a number other than 7 in the ones column, the hint providing unit 15 may determine that the user wants a game content having the value VA. The hint providing unit 15 may generate a hint to be provided in the next lottery process by using the result of determination. In this case, the hint providing unit 15 may provide a hint about an identifier that is associated with a game content having the value VA, for example.

When the server apparatus 1 obtains an identifier, the server apparatus 1 may search for and obtain a game content corresponding to the identifier and may output the game content to the terminal apparatus 2. At this time, the hint providing unit 15 may further provide a hint.

The user can output a reset request to the server apparatus 1 at any time point by using the terminal apparatus 2. When receiving the reset request, the reset unit 16 may reset associations between identifiers and game media and may modify the associations. At this time, the reset unit 16 may update revisions of the lottery history and the hint history or may delete the histories.

After resetting, the hint providing unit 15 may provide the same number of hints as the hints provided before resetting to the terminal apparatus 2.

According to the exemplary embodiment described above, a user may input one identifier in one lottery process. However, a user may be allowed to input a plurality of identifiers in one lottery process. In this case, the hint providing unit 15 may provide one hint each time one game content is output.

In the embodiment described above, the game content output unit 14 may output a game content and the hint providing unit 15 may provide a hint in a lottery process. However, the hint providing unit 15 may provide a hint when the user of the terminal apparatus 2 interacts with another user. For example, a hint may be provided when the user of the terminal apparatus 2 makes a friend request or a request for returning from an inactive state, entices another user to participate in the game, or gives a game content. A user returning from an inactive state may indicate a user logging in to the game system after a certain period over which the user has not logged in to the game system.

The hint providing unit 15 may change the number of hints in accordance with a difference in status information in the game system between users interacting with each other. Specifically, the hint providing unit 15 may increase the number of hints to be provided as a difference in the level, deck strength, play time, and/or progress of a quest, for example, between the users becomes larger.

The hint providing unit 15 may provide a hint when the user of the terminal apparatus 2 clears a predetermined game or a predetermined event in a game. The hint providing unit 15 may provide a hint in accordance with the state of participation of the user of the terminal apparatus 2 in a game or in an event in a game. For example, the hint providing unit 15 may provide a hint when a user logs in to the game system for the first time, when the login rate exceeds a predetermined value, when the login rate is improved, and the like.

In the embodiment described above, the identifier output unit 12 may output identifiers that have not been obtained by the identifier obtaining unit 13 so as to allow the user to only input an identifier that has not been selected in a lottery. However, according to an exemplary embodiment, the identifier output unit 12 may also output identifiers that have been obtained by the identifier obtaining unit 13 so as to allow the user to input an identifier that has been selected in a lottery.

In the embodiment described above, the case has been described where the server apparatus 1 performs two lottery processes. According to another exemplary embodiment, the server apparatus 1 may perform any number of lottery processes, and the process described as the second lottery process may be performed in a third or subsequent lottery process.

In the embodiment described above, the identifier output unit 12 of the server apparatus 1 may output identifiers to the terminal apparatus 2, and the identifier obtaining unit 13 may obtain an identifier selected through a user operation from among the output identifiers. According to another exemplary embodiment, the server apparatus 1 may not include the identifier output unit 12. That is, the identifier obtaining unit 13 may obtain an identifier that is selected by a user regardless of identifiers output by the identifier output unit 12.

In the embodiment described above, when a user selects one identifier, the identifier obtaining unit 13 may obtain the selected one identifier, and the game content output unit 14 may output one game content that is associated with the identifier. However, according to another exemplary embodiment, the identifier obtaining unit 13 may receive an output request for outputting a certain number of game media together with a selected identifier, the request being made in accordance with the user's choice. According to this embodiment, the game content output unit 14 may output game media that are associated with the certain number of identifiers including the selected identifier and an additional (bonus) game content.
